If you are using a wrench to loosen a very stubborn nut, you can make the job easier by using a "cheater pipe." This is a piece

of pipe that slides over the handle of the wrench, making it effectively much longer. Explain why this would help you loosen the nut.

Answer:

Explained

Explanation:

The cheater pipe extends the wrench in radial direction, providing a larger momentum for the force you exert.

For a given force the torque exerted with the cheater pipe is larger.

Mathematically we can write that

τ = r×F and τ'= r'×F

now since r'> r

⇒ F'>F

Answer:

When we use the “cheater pipe” torque increases and loosening the nut becomes easy.

Explanation:

The formula for the torque is given by,

T = rF ……….. (i)

Where,

r = moment arm

F= Force exerted by hand

When “cheater pipe” is used, there is increase in the moment arm and consequently increase in applied torque to nut at constant force. Due to this reason loosening the nut using “cheater pipe” becomes easy.
